Stent
Stent
Stents that release drugs; ureteral or urinary stents; coronary stents
A stent is a small tube that is inserted into a bodily cavity. This structure may be an artery, a vein, or something else entirely, like the ureter, the tube that delivers urine. The structure is kept open by the stent.
Description
The process of inserting a stent into the body is known as stenting. Different types of stents exist. Most are composed of a mesh-like substance, either plastic or metal. Stent grafts, on the other hand, are constructed of cloth. Larger arteries employ them.
A coronary artery stent is a tiny metal mesh tube that expands on its own. It is inserted following balloon angioplasty into a coronary artery. The stent keeps the artery from shutting again.
A medication is coated on a stent that elutes drugs. This medication aids in preventing the arteries from shutting again. It is left in the artery permanently, just like other coronary artery stents.
A stent may be necessary to maintain blood flow in the event of a blocked artery in the neck, legs, or heart in order to avert more catastrophic issues. Today, let’s discuss stents. A stent is a small tube that is inserted into an artery, blood vessel, or other duct (such the urine duct) to keep the tubes open. A stent is implanted for life. The majority of stents are composed of plastic or metal mesh. Larger arteries are frequently treated with fabric-based stent grafts. Numerous arterial issues as well as other conditions are treated using stents. Your physician will make a tiny incision in a blood vessel in your groin to insert a thin, flexible catheter.
Why the Procedure Is Performed
Stents are typically utilized when arteries narrow or become clogged.
The following problems caused by clogged or damaged blood arteries are frequently treated using stents:
- Heart stent implantation and angioplasty for coronary heart disease (CHD)
- Disease of the peripheral arteries (angioplasty and stent replacement)
- Stenosis of renal arteries
- Abdominal aortic aneurysm (endovascular aortic aneurysm repair)
- Disease of the carotid arteries (carotid artery surgery)
Stent usage can also be justified by:
- maintaining an open ureter due to injury or obstruction (percutaneous urinary operations)
- Managing aneurysms, such as those of the thoracic aorta
- Maintaining bile flow in biliary strictures, which are clogged bile ducts.
- Assisting you in breathing in the event that your airways are blocked
